Allow linker initialization of lazy instance
Using the initializer list construct = {0} allows the object to be linker initialized.
Modify the LazyInstance class design to make it a pod aggregate type that can be linker initialized this way. Also combines the instance and state members, in line with the Singleton<> class design.
Introduces a new LAZY_INSTANCE_INITIALIZER macro specifically for using to init all lazy instances + modify all existing callsites to use it. (Old code would no longer compile)
BUG=94925
TEST=existing tests pass. http://build.chromium.org/f/chromium/perf/linux-release/sizes/report.html?history=150&header=chrome-si&graph=chrome-si&rev=-1 should step downward.
